METHOD OF MANUFACTURING TILES.

SPECIFICATION forming part of Letters Patent No. 666,963, dated January29, 1901. Application filed October 4, 1900. Serial No. 31,944- (Nospecimens.)

To all whom it may concern:

Be it known that we, BERNARD JAOQUART, a resident of South River, in thecounty of Middlesex and State of New Jersey, and JOHN FRANCIS BOORAEM, aresident of the borough of Manhattan, in the city and State of New York,citizens of the United States, have invented a new and usefulImprovement in Methods of Manufacturing Tiles, of which the following isa specification.

Our invention relates to an improvement in the method of manufacturingtiles, and relates more particularly to the method of manufacturing thinenameled tiles in the wet process, whereby a thin tile may besuccessfully manufactured which will be perfectly straight whencompleted.

In the accompanying drawings, Figure 1 represents a face view of abrick-blank from which a bull-nose return-tile is formed. Fig. 2 is anend view of the same. Fig. 3 is a top plan View. Fig. 4 is a top planview of the blank after the tile portion has been partially severed fromthe refuse portion of the blank. Fig. 5 is a section taken in the planeof the line 5 5 of Fig. 4:. Fig. 6 is a section taken in the plane ofthe line 6 6 of Fig. 4. Fig. 7 is a top plan view of the refuse portionof the brick-blank after it has been severed from the tile. Fig. 8 is atop plan view of the tile. Fig. 9 is a View in isometric perspective ofthe tile. Fig. 10 is a view in isometric. perspective of a fullreturn-tile without the bullnose. Fig. 11 is a View in edge elevation ofa brick-blank from which a straight enameled tile is formed. Fig. 12 isan end view of the same. Fig. 13 is a top plan view. Fig. let is a topplan View of the blank after the tile portion has been partially severedfrom the refuse portion of the blank. Fig. 15 is a transverse sectiontaken in the plane of the line 15 15 of Fig. 14. Fig. 16 is a top planView of the refuse portion of the'blank after it has been severed fromthe tile. Fig. 17 is a top plan view of the straight tile, and Fig. 18is an isometric perspective View of the same.

In manufacturing thin tiles in the wet process there has been greatdifficultyin keeping the tiles straight and avoiding warping the samewhile being burned in the kiln. To obltile which is held perfectlystraight while being burned, the refuse portion being very readilyremoved from the tile after it has been completed, which refuse portionmay be again utilized in the man ufact ure of the brickblank, andbecause of its having once been burned it serves to lessen the shrinkageof the new blanks thus formed from the material.

We will proceed to describe our improved method of making tiles.

A blank is formed of the full size ofa brick by the wet process commonlyused. While the brick-blank is in its wet state, the portion of the samewhich is to form the tile is nearly severed therefrom. When it is'intended to manufacture a straight tile, the tile portion a of the blankA is nearly severed from the refuse portion or, by forming in theopposite faces of the blank two deep inwardly-extended kerfs a aextending the entire length of the blank and leaving a long narrow webof solid material connecting the refuse portion with the tile portion.When a return-tile is to be formed, the kerfs a a extend from one end ofthe blank to a point a short distance from the other end of the blankbetween the tile portion a and the refuse portion ct of the blank A,where they meet a kerf a which completely severs the return portion a ofthe tile from the refuse portion a of the blank. These kerfs may beformed in any desired manner and at the required distances from thefaces of the tiles. The faces of the tile portion of the brick may betreated to an enamel coating either before or after the kerfs areformed, as may be found convenient. The blank is then completely driedand burned in a kiln in the usual manner. Because of the connectionbetween the refuse portion and the. tile portion the tile portion isprevented from warping. Af-

ter the brick-blank has been completely dried and burned the refuseportion a may be readily broken away from the tile portion a.

This process enables us to form a full return-tile, which has hithertobeen impossible in a thin tile. This process also enables us to save alarge amount of material in each tile, serving the double purpose ofenabling us to construct a very thin facing-wall and also saving thecost of the additional material which it has heretofore been necessaryto utilize in the drying process.

What we claim is 1. The method of manufacturing returntiles consistingin forming a brick-blank, then nearly severing the tile portion in onedirection and Wholly severing it in the opposite direction from therefuse portion of the blank, while in its wet state, then drying andburning the blank and finally separating the tile from the refuseportion of the blank, substantially as set forth.

2. The method of manufacturinga thin enameled tile consisting in forminga brickblank, nearly severing the tile portion from the refuse portionof the blank by forming deep kerfs in its opposite faces While in itswet state, drying and burning the blank,

coating the face of the tile portion of the blank With an enamelintermediate the formation of the blank and the drying and burn- ,ing ofthe same and finally separating the tile portion from the refuse portionof the blank, substantially as set forth.

In testimony that we claim the foregoing as ourinvention we have signedour names, in presence of two Witnesses, this 21st day of September,1900.
